Question

-2x-y=-1 how do you put this in slope-intercept form y=mx=b ?

Answer 1

use 2 step process
1. take everything except the y term to the right side

-2x-y=-1 ----> -y = 2x - 1

2. divide each term by the coefficient of the y term, in this case by -1
-----> y = -2x + 1

after a few of these, you will be able to do that mentally
